feat(codex): route hard-locked main-account traffic to a configured fallback model (carry #7123) - #7146
Conversation
…allback model The main-account hard lock (#5694) refuses requests once the 5h window reads its 90% threshold or the weekly window reads 98%, and a monthly-only account governs on monthly. On a single-account setup that refusal is the whole session: Codex Desktop and CLI turns fail until the window resets even though another provider in the same config could serve the turn. Add extended settings to the same feature: codexMainAccountHardLockFallback names a model and an optional reasoning effort, and while the lock blocks, a qualifying request is rewritten to that selector instead of failing. The rewrite is bounded on every side so it never widens what the lock protects: - It fires only while the lock reads blocked; release stays the same fresh observation that admits, so the reroute ends with the lock, on its own. - getEligiblePoolAccounts is the dispatch's own eligibility choke point, so a usable Pool account keeps the request on Codex; an empty eligible list is what makes the fallback the only way through. - Only bare Codex-native selectors qualify. Provider-qualified rows, combos, account namespaces, policy routes and thread spawns name their own destination on purpose; Luna Reserve keeps its own admission. - A Codex-native fallback target never applies -- rerouting gpt-* to gpt-* would re-enter the same refusal, so the honest behavior is the refusal. - A malformed section disables the reroute entirely, the same disable-don't-widen reading the compaction override takes. The management API projects the section in GET /api/settings, validates PUTs against a strict schema before mutation, and null clears it. The dashboard's main-account protection card grows the model and effort fields with the same acknowledged-write contract as the toggle. The usage log keeps reporting the selector the client asked for.
…tial boundaries Pass the model's quota scope and respect Direct account mode when consulting getEligiblePoolAccounts so a pool account in a shared reset-derived cooldown or an unused pool under Direct mode cannot suppress the hard-lock fallback. Exclude nativeAlias combo selectors from source rewriting, reject canonical openai/<native> fallback targets alongside bare native ids, yield to non-combo shadow-call targets and compaction_trigger turns, mark credential-domain rewrites so caller ChatGPT headers and native reasoning ciphertext are stripped on fallback routes, preserve requestedModel and lane combo recall when routing to a fallback combo, include codexMainAccountHardLockFallback in Desktop compatibility routing preflight, and re-enable paused GUI fallback settings when picking a model.

505-528: 📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low value
⚠️ Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.Fix: the test title and trailing steps do not match the assertions.
The test is named "pauses without forgetting the model, then resumes". It ends with a comment saying that picking a new model while paused re-enables the reroute. The code that follows clicks the switch again and asserts
aria-pressedis"false". No model pick happens. The comment on Line 525 is stale.The behavior in
changeFallbackModel(re-enable on pick while paused) is not covered here. Another test covers a pick from a paused state only partly. That test starts paused and checksenabled: truein the PUT body, so the behavior is covered. Remove the misleading comment or replace the last three lines with a real pause assertion.Proposed fix
- // Picking a new model while paused re-enables the reroute immediately. - await click(fallbackSwitch(host)); - expect(fallbackSwitch(host).getAttribute("aria-pressed")).toBe("false");gui/src/components/MainAccountHardLockSetting.tsx-300-302: 1

⚠️ Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.Fix: clearing the effort sends
reasoningEffort: undefinedand relies on JSON omission.
JSON.stringifydropsundefinedkeys, so the server receives noreasoningEffort. This works. The intent is unclear to readers. The spread order also hides the clear step. Delete the key explicitly.Proposed fix
- const changeFallbackEffort = (effort: string) => { - void saveFallback({ ...(fallback ?? {}), ...(effort ? { reasoningEffort: effort } : { reasoningEffort: undefined }) }); - }; + const changeFallbackEffort = (effort: string) => { + const { reasoningEffort: _old, ...rest } = fallback ?? {}; + void saveFallback({ ...rest, ...(effort ? { reasoningEffort: effort } : {}) }); + };Also,
saveFallbackacceptsExclude<FallbackSetting, null>, somodelis optional.changeFallbackEffortcan PUT an object withoutmodelwhen no fallback exists. The server schema requires a nonblankmodeland returns 400. The effort select is disabled when!fallbackOn, which blocks this path today. Make the guard explicit withif (!fallback?.model) return;.
